The patients are randomised to either synbiotics or placebo administration at the day they are able to tolerate po liquid diet and for 15 days thereafter.

Primary end points of the study will be:

Assessment of gastrointestinal function-related quality of life at 1, 3 and 6 months postoperatively by the use of the validated questionnaire GIQLI (Gastrointestinal Quality of Life Index)

Secondary end points will be:

-Assessment of functional bowel disorders (diarrhea, constipation, etc) at 1, 3 and 6 months postoperatively based on the respective domains of the validated instrument EORTC QLQ-C30
